A revised window layout allowed us to create a separate toilet room and a large wet room, incorporating a 5′ x 5′ shower area with a built-in undermount air tub. The shower has every feature the homeowners wanted, including a large rain head, separate shower head and handheld for specific temperatures and multiple users. In lieu of a free-standing tub, the undermount installation created a clean built-in feel and gave the opportunity for extra features like the air bubble option and two custom niches.
